I saw a slow moving white light traveling silently from north to south. At first I thought it was an aircraft, but then the light came to a complete halt, and then it formed a circle of five small white lights which proceeded to rotate in a clockwise direction. After a couple of minutes, the lights recombined into one unit and continued to travel in a southerly direction.
